Blockage, or impaction, occurs when the wax gets pushed deep within the ear canal. Earwax blockage affects about 6% of people and is the most common ear problem doctors see.
A doctor can diagnose earwax blockage (or eardrum perforation) by listening to the patient's symptoms and then looking into the ear with an otoscope(ear-scope).
The doctor may remove the earwax with a small plastic spoon called a curette, or by irrigating the ear with warmed water, saline, docusate(Colace), sodium bicarbonate, or other prescription-strength eardrops.
Earwax blockage can be prevented by avoiding the use of cotton-tipped swabs or Q-tips and other objects that push the wax deeper into the ear canal.
Over-the-counter wax softening drops, for example, carbamide peroxide (Debrox, Auro, Murine) or warmed mineral oil may be put into the affected ear and then allowed to drain out after about five minutes.
